Description
Technical field
The present invention relates to a kind of generation method and utilization that makes the bionical virtual world of human-computer interaction.
Background technology
Each control piece on the battlebus all need not connect in fact again, but the obvious mechanical control of this traditional approach is many, and cost is high, and carries inconvenience.
Summary of the invention
The purpose of this invention is to provide a kind of user of letting can entering virtual world on the spot in person, and gives the function that self-role enjoys and the equipment of capability approach and use through the corresponding site control virtual world of self fully.
For the ease of understanding the present invention, the spy carries out following explanation of nouns to each related term.
Oneself role: refer in virtual world, can be controlled by the user, and thought own virtual role, the mankind or any movable object space by the user.
The user allows fine motion to make scheme: when the user implements some or the qualified fine motion of a group when doing, can send a steering order to computing machine; The fine motion here especially refers to user's action by a small margin, and less than 20cm, concrete manifestation is like arm fine motion, the little song of pin like: corresponding joint moving displacement arbitrarily; Above-mentioned condition of the present invention especially comprises the situation that qualification is not given an order.
Virtual permission action scheme: virtual world is given action or the action scheme that utensil can carry out in self-role or the virtual world, and said action scheme comprises continuous combination of actions, action dynamics, speed etc.
Turning joint: the user is not the activity that the activity in whole joints can be controlled my role's phase position; When especially self-role is non-human; User some joint on one's body not, so " turning joint " of indication of the present invention is meant that virtual world is given the movable position of self-role and corresponding to the joint on user's actual body.On the other hand, when self-role's movable part is counted more than the actual turning joint of user, the additive method that then adopts the present invention to introduce.
Counteragent: the instruction that the virtual world scene is carried out with the user sends at self-role place has vector value vector action identical but in the opposite direction; Said vector action the present invention especially refers in particular to change in displacement, volume change on the random time point; As shown in Figure 1: with the vector action is ordinate; With time is that horizontal ordinate is set up coordinate system; Then user's instruction of sending concerns with horizontal ordinate with the corresponding curve map of virtual world scene at self-role place axisymmetricly; As: to time point t2, the user will advance 5 meters the time towards southeastern direction from time point t1, just can realize to moving 5 meters as long as on this time period, make self-role belong to the scene northwestward; For another example: from time point t1 to time point t2; The user wants own whole body equal proportion to become big 2 times; Then self-role belongs to scene and dwindles twice in the identical time period; Here especially point out: in user's change body or the distortion instruction, judge whether to comprise the variation of eyes and binocular interval earlier, if eyes and binocular interval do not change; Then scene can not change on volume, i.e. the volume vector of scene action has with the volume vector action that self-role's eyes and binocular interval leave: the relation that vector value is identical, in the opposite direction.
Said counteragent is to make self-role in the virtual world belong to scene to carry out the vector that vector value is identical with self-character head is in the opposite direction and move; And both are being in the coordinate system of coordinate axis with same vector action and time respectively, and its vector action time figure concerns with the time coordinate axle axisymmetricly.
Palm: palm 1 as shown in Figure 2 comprises the joint on all palms of wrist 11, as points 12.
Sole: sole 2 as shown in Figure 2 comprises the joint on all soles 2 of ankle 21, like toe 22.
Estimate the index of motion amplitude: is followed the tracks of displacement that the position takes place and direction, quilt is followed the tracks of the angle of position on two time points.
For realizing above-mentioned purpose, technical scheme of the present invention is:
one,
user can control the various operations that virtual world is accomplished in the position in the same place in reality.
The technical scheme that realizes this technique effect is to adopt the action amplification system; Described action amplification system is meant and sets user or virtual world stage property to carry out the amplitude peak that arbitrary user allows self-role's virtual permission action in the amplitude peak M that moves, the corresponding virtual world be N, on the t time point user or virtual world stage property to carry out the amplitude that this permissions moves be Mt; The amplitude that the execution of people or thing allows to move accordingly in the corresponding virtual world is Nt; Then this system satisfies: as Mt during more than or equal to M, and Nt=N; As Mt during less than M; N lifts 5 when spending greater than Mt like: user's arm greater than Nt, and self-role then lifts arm fully, when the user raises one's hand the angle of arm greater than 5 degree; The oneself role all lifts arm fully; Here, we claim that 5 spend the amplitude peak of carrying out the arm of raising one's hand for the user, and obviously user's arm not only can be lifted 5 degree.
Here especially point out: when nothing deformity and healthy user carry out certain permission action; Actual limit of sports record all allows the amplitude peak of action greater than this; And in order more effectively to realize the present technique effect; When the virtual world process adopts the action amplification system, preferably only allow its fine motion of carrying out by a small margin to do through restriction to user's limbs.
Said user allows fine motion to make scheme to satisfy: when the user accomplished arbitrary fine motion and does with amplitude peak M, the angle changing value of the two any adjacent parts on the trunk except that palm and sole was spent less than 30.As: certain allows fine motion to relate to the angle of upper arm and underarm as scheme, is 120 degree and 140 degree at the front and rear angles of implementing this action, and variable angle value that then should adjacent two parts just is+20 to spend.The present invention can provide perseveration order in addition, and when the user continues elastic device is done the time spent, the user such as can keep turning round at action.Therefore the user can control any action scheme of self-role under free position.In preferred positive and negative 5 degree of amplitude peak M according to the invention.
two,
virtual world receive the method for user instruction.
It is to confirm the action that the user carries out through action anchor point control system, confirms the command content that the user sends through relevant action, controls self-role then to the activity with regard to movable position.
Said action anchor point control system: be on one's body or be provided with the location induction pieces more than 1 or 1 on the virtual world stage property the user; Position (three-dimensional coordinate) through each location induction pieces over time, thereby can confirm that posture that the user goes up at any time or the action in certain period change.
The present technique that below makes introductions all round scheme related " method is confirmed in the variation of induction pieces position, location ", " controlling the method for self-role action through location induction pieces change in location " and " location induction pieces or its change the corresponding method with self-role action or movable position ".
(1) to confirm that method comprises following rapid in the variation of induction pieces position, location:
1) build a virtual three-dimensional coordinate system, and confirm more than three or three and not at the coordinate of the range determination point on the same straight line in this coordinate system;
2) measure location induction pieces branch and be clipped to the distance of above-mentioned each range determination point, respectively locate the three-dimensional coordinate that induction pieces is put at any time thereby calculate.
(2) method of controlling self-role action through location induction pieces change in location is to give self-role A1, A2 to virtual world ... An amounts to n can independent movable position, by following two kinds of situations control:
1) all can find corresponding turning joint to carry out correspondence on one's body when this N movable position the user; Then in each corresponding turning joint, N1, N2 are set respectively the user ... Nn is N location induction pieces altogether; And follow the tracks of when putting t at any time N1, N2 ... The Nn three-dimensional position changes; The three-dimensional position of respectively locating induction pieces is changed, control self-role's corresponding site and carry out relevant action;
2) can not find corresponding turning joint to carry out on one's body the user fully when this N movable position at once; Suppose to exist some movable position Mx that can not find corresponding relation; Make user's turning joint Nx can select to control self-role's Mx1, Mx1 earlier ... Mxs is s movable position altogether, and adopt in back-and-forth method and the combined method a kind of or all select to control concrete movable position Mx; After said back-and-forth method is meant that turning joint Nx confirms corresponding control activity position, directly control separately; Said combined method is meant; When need replacing activity position, can or utilize other turning joints to select to carry out different movable positions jointly through the 3rd order, as: user's arms can select to control self-role's arm and wing; Said turning joint is made as toe; When the toe time-out of curling up, then the user controls wing, unclamps and then controls arm; Said the 3rd order can be jumped out and select the interface when being referred to certain command menu, will control activity position through selecting to confirm.
" control the method for self-role action through location induction pieces change in location " and also comprise dividing movable part and movable portion on user's health and the stage property, and movable part is set an induction pieces respectively; Wherein article or utensil are corresponding in stage property and the virtual world, make when behaviour makees stage property, and respective articles or utensil in the virtual world are done by corresponding behaviour, in other words are exactly with the thing (people or thing) in the induction pieces control respective virtual world, location in fact.
(3) location induction pieces or its variation are to use the location induction pieces on the different joints, family all to have different distinguishing characteristicss with the corresponding method at self-role action or movable position, and move through the corresponding self-role's of different distinguishing characteristicss movable position or difference.
Said distinguishing characteristics is that the difference on the induction pieces of location is coated with dot density or is coated with a rule.
It also comprises in the system that places obstacles at random of olfactory system, haptic system and physical fatigue one or more
three,
.
More tired as system identification oneself role, then the mechanism that places obstacles on the corresponding site is just big more to the load at this position, it is just more difficult that the user carries out this action, reality have a sensation roughly the same, it is truer to play.
four,
the present invention have also introduced a kind of formula that wears fixed point opertaing device that is applicable to above-mentioned virtual world method ".
It comprises palm external member, arm external member, head external member, sole external member, shank external member, buttocks external member and waist external member; Be equipped with one or more induction anchor points on each external member.
It also satisfies: on a joint of 3 points on the same straight line, every toe, ankle joint, shank, thigh, buttocks, vertebra mid point, be not equipped with one or more and respond to anchor point arbitrarily three joints of every finger, wrist joint, elbow joint, shoulder joint, head on.
This equipment is intended to confirm user's on arbitrary time point position and posture fully through being positioned the user position of respectively responding to anchor point on one's body that this equipment also is confined to the allocative decision of above-mentioned induction anchor point in above-mentioned joint.
The method that the health that
five,
the present invention also provide a kind of user to see oneself gets into virtual world.
Implementation method is to adopt the system of staying, panorama system and scene mobile system simultaneously, and each system below makes introductions all round.
(1) said scene mobile system utilizes self-role in the virtual world to belong to the reverse vector action of scene, the user is had just carry out the various illusion that move or become body (health dwindles or amplification or change in shape);
Definite method that said self-role belongs to scene comprises:
1) directly or indirectly is provided with the keeper that can be subjected to displacement synchronously with head at user's head; Do not have at least on the said keeper and can confirm, thereby determine position and the face orientation of user's head in virtual world in collinear 3 positions at virtual world;
2) confirm the virtual world picture through the position and the face orientation of user's head in virtual world;
Said counteragent; Be to make self-role in the virtual world belong to scene to carry out the vector that vector value is identical with self-character head is in the opposite direction and move; And both are being in the coordinate system of coordinate axis with same vector action and time respectively, and its vector action time figure concerns with the time coordinate axle axisymmetricly.
(2) said panorama system makes the user can only see the scene in the virtual world, and can't see the scene in the reality, and the virtual world scene covers whole visual ranges of user; Native system refers to that especially the user wears full 3D glasses, and screen and virtual world picture thereof all cover whole visual ranges of user on the glasses.
(3) the said system that stays, it is synchronously movable to satisfy user's and user's body identical with the position of self-role in virtual world and self-role, when making the user want to see own health, all can see in the virtual world exercises of oneself.
The usefulness of technique scheme is:
" the action amplification system " that the present invention introduces; Can make user's body need not to be subjected to displacement or only to take place repertoire or the ability that micro-displacement just can realize that whole virtual worlds are given; Make the user in virtual world whole process, all only control on the position at same place; Be convenient to also simultaneously realize that user's motive position is consistent with virtual world personage motive position, make the user easier left-hand seat.
" wearing formula fixed point opertaing device " that the present invention introduces, the user is directly dressed after, each action partly of health; All may command corresponding " induction anchor point " is carried out related command; Thereby make the user see that the own or own apparatus of in virtual world, controlling carries out relevant action, the setup time of user before getting into virtual world effectively shortened in the utilization of this equipment; Simple and easy required preparatory process, thus the user just can carry out virtual world through convenient mode very.
" the induction anchor point system " that the present invention introduces can make each vector that each anchor point of control device perception takes place change (comprising: displacement, speed, direction), can effectively simplify " wearing formula fixed point opertaing device "; Make it pure, and need not to join fully any electronic system, because the user in use with physical construction; Each anchor point all is located in user's each corresponding position on one's body; Each position activity space of tool user is limited, therefore can do equipment zero infringement, promptly guarantees the serviceable life of equipment; Because of no institute electronic system can avoid electrical short to bring actual bodily harm to the user.
" back-and-forth method " and " combined method " that the present invention introduces can realize that self-role goes up the movable part figure place and counts greater than the induction location.

The user is maximum to allow fine motion to make restriction system
Present embodiment is for making virtual world more true to nature, comprises in the systems that place obstacles at random such as olfactory system, haptic system and physical fatigue one or more; The system that places obstacles at random of said physical fatigue can combine to wear formula fixed point opertaing device, establishes a contractile device of holding as connecting in a telescopic propulsive mechanism, the palm external member on the sole external member.The said system of placing obstacles comprises the retroaction sensing device and is applied sensing device; The said sensing device that is applied satisfies: when the arbitrary object space in the virtual world acted on self-role's a part or some position, the system of placing obstacles can act on user's the corresponding site according to this object space motion characteristic; The retroaction sensing device satisfies: when self-role effect during in the arbitrary object space of virtual world; System is at first according to the immediate status of self-role's motion characteristic and this object space; The self-role who judges is by counteractive position and reaction result, said place obstacles system then with etc. factorial effect act on the corresponding position of user.The said system that places obstacles changes the retroaction sensing device and is applied the load of sensing device to the user according to self-role's degree of fatigue and largest motion ability.
Below pass through case introduction:
Want earlier the user to be fixed on certain before the virtual world and control position upward (as: on the bed); The arbitrary limbs of user action; Corresponding personage in virtual world then carries out completely action, and purpose is that the user carries out any action and can control the position at same place and carry out, after the action; The health position can not change yet, thereby reduces user's space.
Let the user lie in or be sitting on the control desk, make the FROM of each trunk of system constraint user of placing obstacles, as: sole device Elastic Contact user's sole; The arm stop means is placed on user's arm far to be full of to cooperate.
The said mechanism that places obstacles is located at above the position that the user allows to move; Make place obstacles mechanism and user's trunk keep certain distance (being called free space) under normal conditions; Make each position of user under the situation that does not touch the mechanism that places obstacles, can not receive effect to carry out any meaning fine motion and do; The said mechanism that places obstacles is provided with elastic load behaviour area (being called the load space), when user's trunk contacts with the mechanism that places obstacles, and continuous continuing when moving in the other direction toward elastic force, corresponding site need overcome the elastic force work done.Its function is corresponding as follows:
1) user makes amplitude in the movably summation in free space and load space corresponding to user's maximum permission fine motion;
2) act on the mechanism that places obstacles when user's trunk, its action simultaneously meets machine when calculating the machine recognition command; The oneself role continues to carry out virtual permission action, as: turn round continuously;
3) when the user inspires human-computer interaction, the mechanism that places obstacles shows as the retroaction of target to the user;
4) done the time spent by the object space in the virtual world as self-role, the mechanism that places obstacles dwindles free space, and acts on user's corresponding trunk;
5) when self-role movement ability value promoted, the load of the mechanism that places obstacles reduced;
6) when self-role movement ability value weakens, as: when tired, the load of the mechanism that places obstacles improves.
The described induction anchor point of present embodiment can be suitable for following two kinds of schemes:
1) is coated on the sensitive spot of muscle as the induction anchor point surveying coating,, makes the intention of the induction anchor point ability judges on each strand meat, thereby effectively virtual world is sent command adapted thereto through the tensity and the movement velocity of muscle;
2) will respond to anchor point is fixedly arranged on each the movable position that wears formula fixed point opertaing device; After the user is directly dressed; Each action partly of health, all may command corresponding " induction anchor point " is carried out related command, thereby makes the user see that the own or own apparatus of in virtual world, controlling carries out relevant action; The utilization of this equipment; Effectively shorten the setup time of user before getting into virtual world, simple and easy required preparatory process, thus the user just can carry out virtual world through convenient mode very.
Above-mentioned two schemes are not limited to " action amplification system ", and especially be directed against and do not require the object for appreciation virtual world that user's body is subjected to displacement, as: the racing car virtual world.
Wear in the present embodiment formula fixed point opertaing device also can be in equipment implant controller, make each vector that each anchor point of control device perception takes place change (comprising: displacement, speed, direction); But in conjunction with " induction anchor point system " that the present invention introduces, cocoa is effectively simplified " wearing formula fixed point opertaing device ", makes it pure with physical construction; And need not to join fully any electronic system; Because in the virtual world process, each position of user is only carried out fine motion and is done the zero infringement of the equipment of therefore can doing; Promptly guarantee the serviceable life of equipment, can avoid in institute's electronic system possible electrical short to bring actual bodily harm again to the user.
Wear formula fixed point opertaing device in the present embodiment and comprise palm external member, arm external member, head external member, sole external member, shank external member, buttocks external member and waist external member; Be equipped with one or more induction anchor points on each external member.
It also satisfies: on a joint of 3 points on the same straight line, every toe, ankle joint, shank, thigh, buttocks, vertebra mid point, be not equipped with one or more and respond to anchor point arbitrarily three joints of every finger, wrist joint, elbow joint, shoulder joint, head on.
This equipment is intended to confirm user's on arbitrary time point position and posture fully through being positioned the user position of respectively responding to anchor point on one's body that this equipment also is confined to the allocative decision of above-mentioned induction anchor point in above-mentioned joint.
Especially point out:
1) for guaranteeing to move the validity of amplification system, self-role's permission action executive condition be not the induction anchor point at a time between on the position, but go up the change in location on the time point relatively;
2) the range determination point is fixed, and perhaps its coordinate can calculate and confirm;
3) some virtual world in order to reduce taking of computer resource, is only given the very specific several actions of self-role, in this case, should satisfy the action or the combination action at some position of user, just should control self-role and carry out one and connect the permission of being used to and move;
4) the action amplification system can make up utilization with action anchor point control system, also can use separately;
5) the present invention also comprises speech control system, makes the user to send instruction with the permission action of controlling self-role and each item basic operation of virtual world through voice, as: withdraw from, preserve.Native system also comprises speech recognition system, as can be to user's sound typing in advance, and the coupling instructions.
Other explanations:
After the user is ready, the position of opening eyes and can find to control oneself and belonging to when once withdrawing from virtual world last, the variation of the scene that exercises brought is a starting point from this position fully.
Does greater than people's pass joint number what if this virtual world allow self-role to have deformability needs control after distortion position? Can adopt back-and-forth method when carrying out the select command action, can select in certain joint control virtual world concrete motive position picture; Also can adopt combined method is two or more joints when carrying out certain specific action simultaneously, also can play same effect.
This virtual world method also allows the user to have separated sky and gets Extra Sensory Perceptions such as thing, and the entry condition of this instruction is: induction on user's arm location point set on same straight line, the integrated claw-like of induction anchor point on the palm and towards these article; And virtual world is judged the size of suction, then can be scheduled to self-role's suction maximal value earlier, and the condition of value can be the frequency that finger is shaken, and when frequency reduces, then the suction correspondence reduces.
Receive this intention of user when virtual world, will calculate and suction and the article difficulty of being inhaled relatively, when the gravity of article too greatly or too big by the suction power of former position; Just send out putting more effort of asking the user to use to grab; At this moment the degree of crook of finger will be strengthened, and the shake of finger aggravation, and make the induction anchor point shake aggravation on the finger; Computer will be received the reinforcement of user's suction, thereby further can judgement accomplish absorption.
The location induction pieces with the position that will control how corresponding? If all corresponding location induction pieces in each joint; In the virtual world that abundant permission action is arranged, just need the user to prepare for a long time just possibly get into virtual world; The present invention also provides and has worn formula fixed point opertaing device for this reason "; the user only need wear corresponding gloves, footmuff, support casing and the helmet, just can control the induction anchor point of tying up on the joint, every place that overlays on whole body, therefore has practicality.
Owing to adopt the action amplifying method; The user has health and each position of self-role and posture not corresponding fully; Therefore can not singly confirm with the position of induction anchor point, but the position of both heads (is eyes by it) in virtual world with towards being identical.How does that explain that the user also can confirm coordinate at virtual world? At first user's vision obtains through glasses; Those glasses are confirmable at the coordinate of virtual world; Because the relative position of eyeball and glasses is constant all the time, therefore, user's eyeball can be decided at the coordinate of virtual world.
